net: hns: Fix for variable may be used uninitialized warnings
When !CONFIG_REGMAP hns throws compiler warnings since dsaf_read_syscon ignores the return result from regmap_read, which allows val to be uninitialized. Fixes: 86897c9 ("net: hns: add syscon operation for dsaf") Reported-by: Jason Gunthorpe <jgg@ziepe.ca> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: Yunsheng Lin <linyunsheng@huawei.com> Signed-off-by: David S.
